COMBINED CAP-EXTRACTOR AND SANITARY BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Mar. 22, 1921.

Application filed September 4, 1919. Serial No. 321,691.

To all whom it may concern.

Be it known that I, GEORGE A. VYETH, a citizen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Combined Cap-Extractors and Sanitary Bottle-Closures, of which the following is a specification.

My invention relates in general to a combined cap extractor and sanitary bottle closure of the type of such devices which aredesi ned to engage and remove from milk bott es and the like, the paper disks usually employed as closures on such bottles, and to furnish a sanitary means of closure to bottles thereby preventing contamination to contents.

The primary object of the invention is to provide a simple means for readily removing the usual paper cap closures and at the same time to provide a simple form of metallic,

closure which can be quickly secured to and removed from the mouth of the bottle and which will utilize the usual paper disk as a replaceable gasket to insure the sealing of the bottle and coact therewith to effect a closure capable of resisting to a large degree any accidental removal of the paper gasket.

Such construction, as heretofore designed,

I includes a cap engaging member designed to make an incislon through the cap for the purpose of anchoring the closure to the cap and for the purpose of facilitating the Withdrawing of the paper cap from thebottle. These cap Withdrawing constructions, however, have been objectionable in that they are apt to cause the pa er cap especially if frail, to buckle inwar ly against the contents of the bottle and under some conditions are apt to tear the cap thus destroying its value as a sealing element.

Accordingly, another obj eet of the invention is to furnish an absolutely sanitary closure for top of bottles. completely covering the entire pouring surface of same and thereby preventing contamination by flies, insects, dirty hands, etc. Further, another object of the invention is to provide a type of cap anchor which will form a clear inci sion through the cap and which will coact with the incision thus formed to secure the paper cap to the bodv portion of the anchor carrying closure.

Still another ob 'ect of the invention is to provide a device of the tVDe above outlined WhlCh can be manufactured economically so that it can be marketed at low cost. Featurlng this phase of the-invention there is contemplated the providing of a one-piece tion, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the accompanying drawings Figure 1 is a perspective rim of the upper portion of a bottle showing a preferred embodiment of the invention positioned thereon:

Fig. 2 is a vertical sectional view taken centraally through the device shown in Fig. 1; an i Fig. 3 is an enlarged detail view ofpart of the closure shown in the preceding figure and inverted to show one of the anchors.

In the drawings, there is shown a bottle neck 10 provided with a throat 11, and the upper edge of which neck is rounded to provide a mouth 12. The neck is provided with the usual countersunk seat 13 positioned within the throat and spaced downwardly from the mouth 12. A paper cap 14 is positioned on the seat and acts to close the throat as is usual in some jars and bottle constructions such as the milk bottles in general use.

The closure 15 particularly forming the subject matter of this invention is a onepiece, sheet metal stamping which is made of as thin a metal as will withstand the strainsto which such devices are intended to be subjected. The closure is formed in general of a body portion which includes a countersunk central disk 16 which fits flat on top of the aper cap 14.- and has a diameter substantia ly equal to that of the paper cap so that the disk and cap coact to form a doublela or thickness of material across the throat o the bottle as shown in Fig. 2. A peripheral flange 17 outlines the disk16 and rounds upwardly and outwardly therefrom so as to .inclose the mouth 12 within the groove 17 These spring fingers are pressed inwardl 1 so that they will engage the side of the nec below the mouth and hold the closure resiliently in position and against accidental knocks which may tend'to displace the same and accommodate different sized bottles. The central disk is likewise slitted at three circumferentially spaced apart points to form pointed downwardly extending projections 21 hereinafter referred to as anchors. It is understood that these anchors are formed by slitting the body portion of the container and bending the anchors at ri ht angles to the plane of the disk. These anciors are V-shaped in horizontal cross-section and with their pointed ends act on the paper disk when forced into engagement therewith, to form a V-shaped incision in the disk. This causes the disk to adhere firmly to the anchors. The edges of the anchors are serrated as shown at 22 which serrations have the effect of preventing the easy withdrawal of the closure from the cap when an attempt is made to elevate the cap by lifting the closure as hereinafter more fully described. One anchor is suflicient to attach the closure to the cap, and to elevate the same but the three anchors disclosed are preferred. Elevators 23 inthe form of diametrically extending and outwardl exposed tabs project from opposite si esof the peripheral flange and are preferably disposed in alinement with the anchor when but one anchor is used.

relation of elevators to anchor is of advantage especially when a resilient form of closure is used for, as the closure is lifted off the bottle, the tendency of the anchors is to spring outwardly toward the periphery thus holding the paper cap more firmly and insuring the positive withdrawing of the same from the bottle.

As the metallic closure firmly engages the bottle at the side of the neck, any tendency of the bottle, as in turning over to displace the paper cap is resisted by the closure, thus providing a sanitary form of closure which can be used repeatedly while the paper cap can be replaced with each new filling of the bottle. 1

As the entire closure can be formed from one-piece by a simple stamping operation there is effected a material saving in the manufacture and cost.

While I have shown and described, and have pointed out in the annexed claims, certain novel features of my invention, it will be understood that various omissions, substitutions and changes in the form and details of the device illustrated and in its operation may be made b those skilled in the art without departing rom the spirit of the invention.

Having thus described my invention, I claim 1. A one-piece closure for a bottle of the type usually closed with a paper cap, said closure including a central disk, a peripheral flange outlining said disk and adapted to fit over the mouth of the bottle, a holding clip dependingfrom the outer edge of said flange and adapted to engage the outside of said central disk and adapted to perforate the paper cap, said anchor bein V-shaped in cross section in a plane paralle to the disk to form a V-shaped incision in the paper cap.

2. A one-piece closure for a bottle of the type usually closed with a paper cap, said closure including a central disk, a peripheral flange outlining said disk and adapted to fit over the mouth of the bottle, an anchor depending from said central disk and adapted to perforate the paper cap, said anchor being V-shaped in cross section to form a V- shaped incision in the paper cap and having serrated edges.

3. A one-piece sheet metal. closure for a bottle including a peripheral flange adapted to fit over the mouth of the bottle, a spring clip depending from said flange, provided with a pair of slits forming a spring finger adapted to bear on the outside of the bottle to hold the closure in place and said closure provided with a air of slits forming a pointed cap engaging anchor.

4. A one-piece sheet metal closure for a bottle including a central cap engaging disk and a peripheral flange integral therewith, and outlining the same, said closure having a plurality of slits cut therein, the metal between certain of said slits being bent from the slitted portion to form spring clips for engaging the bottle, the metal between certain other slits being bent from other slitted portions to form a cap engagi anchor.

5. A oneiece sheet metal 0 osure for a bottle inolu ing a cap-engaging disk provided with a pair of slots spaced from the edge and converging to a point to form a pointed finger, said finger being pressed from the disk at right angles thereto to form an anchor adapted to perforate the usual paper caps constituting the closure for certain types of bottles.
